Abstract: The selection of a keyboard on a computer system can automatically be achieved. If an externally pro­vided keyboard (18) which transmits transmission data upon the turning on of a computer system is connected to an external keyboard controller (16), a selection cir­cuit (14) selects that external keyboard controller (16) for controlling the externally provided keyboard (18). If, on the other hand, no externally provided keyboard (18) is connected to the external keyboard controller (16), the selection circuit (14) selects an incorporated keyboard controller (15) for controlling an incorporated keyboard (17) which is incorporated in the computer system. When the externally provided keyboard (18) is connected to the external keyboard controller (16), the selection of a keyboard by the selection circuit (14) is achieved depending upon whether or not the computer system receives transmission data from the externally provided keyboard (18).

Abstract: A microprogram controlled microprocessor capable of normalizing a given data in a floating point representation includes a memory storing a microprogram, an address register for holding a microprogram start address, an operand register for holding a source operand, a temporary register for temporarily holding an operation data, a pointer for holding a code indicative of the operand register at the time of starting the microprogram and for indicating a transfer source register in a transfer operation between internal registers, and a discriminator for discriminating whether or not an input source operand is a normalized number. The microprocessor operates on the basis of the microprogram to execute a given operation to the input source operand while causing the discriminator to discriminate whether or not the input source operand is a normalized number, so that the microprogram is completed without a branch when the input source operand is a normalized number. On the other hand, when the input source operand is an unnormalized number, the microprocessor operates to branch to a normalizing program and to cause a normalized operand to be held in the temporary register and a code indicative of the temporary register to be set to the pointer. In addition, the microprocessor operates to re-execute the microprogram from the address designated by the address register.

Abstract: Es wird ein Verfahren und eine Einrichtung vorgeschlagen, welchem die Aufgabe zugrundeliegt, Lastmomentschwankungen zu reduzieren und die Beanspruchung eines Antriebs herabzusetzen. Insbesondere bei einer Druckmaschine treten drehzahlabhängige, zyklisch wiederkehrende Lastmomentschwankungen auf. Diese können im Antriebssystem zu elastischen Verformungen führen, die eine Qualitätsbeeinflussung des Druckprodukts zur Folge haben. Es wird daher vorgeschlagen, daß der Erhöhung eines Lastmoments dadurch entgegengewirkt wird, daß das Antriebsmoment verringert wird, und damit eine Drehzahlreduzierung erfolgt, wobei die Größe der Drehzahlreduzierung so bemessen ist, daß das entstehende Lastmoment näherungsweise auf einem konstanten Wert verharrt.

Abstract: The invention is an automatic gain control (AGC) sampling structure for use with frequency-hopped high frequency waveforms containing known transmitted signals embedded within communi­cation traffic. The sampling structure is a digital structure and an automatic gain control selection algorithm used in conjunction with a standard close loop analog automatic gain control circuit in which the automatic gain control generator (26) detects the received audio level and generates a direct current control voltage for controlling an amplification stage (20). This automatic gain control voltage is sampled during the reception of known transmitted signals to provide a series of independent automatic gain control samples to a digital controller (34). The digital controller (34) determines the optimum automatic gain control voltage based on a selection algorithm which uses the technique of altered statistics to select the correct ordered sample to provide the optimum automatic gain control level for the receiver. The standard automatic gain control loop is then interrupted and the optimum automatic gain control voltage selected by the digital con­troller (34) is coupled to provide the direct current control voltage to the amplification stage (20).

Abstract: Detail enhancement is achieved by producing an enhanced image signal (ES) on the basis of a sharp signal (S), a middle signal (M) and an unsharp signal (U). The sharp signal represents density of a pixel, the middle signal represents weighted means density of a first area larger than a pixel and the unsharp signal represents weighted mean density of a second area larger than the first area. Three differential signals (S - M, S - U, M - U) are obtained and multiplied by respective coefficients to become three enhancement signals. The enhanced image signal is obtained by adding the sharp signal and at least one of the three enhancement signals so that the detail enhancement is achieved at a middle range of spatial frequency.

Abstract: The three titration faces lie in a Cartesian coordinate system, with one outer face remote from the zero of the coordinate system. The plane-parallel elements are partly mutually orthogonal, and partly with the parallel sides next to each other. The elements always lie parallel to one of the planes of the Cartesian coordinate system. The outer face of the tetrahedron has a centre, and the elements are of increasingly reduced size towards the centre. The straight line between the centre and the zero of the coordinate system is the displacement straight line along which the Cartesian coordinate system has moved to form intersecting faces.

Abstract: A control processor in a robotic system treats optically sensed locations along the path ahead of the tool, which are classified in relation to elapsed distances and identified in 3-D coordinates and 3-axes tool orientation, to apply in real time and under feedforward a control signal representing the error between anticipated tool position and anticipated sensed location on the path. In the process, the anticipated sensed location is obtained by reference to a model made ahead of time with the stored sensed locations grouped as a function of elapsed distances and having a common algebraic feature, such as the slope or the change of slope. A taught path for the robot has been recovered by the control processor also based on elapsed distances and control is related to actual tool position provided by the robot.
